Titanium Seamless Pipes, often manufactured to ASTM B861 standards, are characterized by their exceptional strength-to-weight ratio and high ductility. These pipes, created without any welding seams, exhibit tensile strengths ranging from approximately 30,000 to 200,000 psi. The natural formation of a passivated oxide coating provides inherent corrosion resistance. This makes them ideal for applications requiring high structural integrity and reliability in demanding environments.
Titanium Welded Pipes, produced in accordance with specifications like ASTM B862, offer a robust and lightweight solution. Despite having only 56% of steel's density, they achieve tensile strengths comparable to many alloy steels. Their corrosion resistance is remarkable, similar to platinum, due to the protective oxide film that forms on the surface.

Yes, titanium pipes are an excellent choice due to their exceptional strength-to-weight ratio and high corrosion resistance. They are lightweight yet incredibly strong, making them ideal for demanding industries like oil and gas, aerospace, and marine applications. Their durability and resistance to harsh environments make them a preferred option over traditional materials.
While the initial cost of titanium piping is higher compared to materials like graphite, ceramic, PTFE, or glass, it proves to be a cost-effective investment in the long run. Titanium pipes have an extended lifespan, often lasting for decades with proper maintenance, reducing overall replacement and maintenance costs.
Titanium pipes are manufactured in a wide range of sizes and thicknesses, adhering to industry standards like ASTM B861 (seamless) and ASTM B862 (welded). Outer Diameters (OD): These range from very small (fractions of an inch) to very large (several feet), commonly from 1/8 inch NPS to 24 inches NPS and beyond, depending on the application. Wall Thicknesses: These vary significantly based on the "schedule" (e.g., SCH 5, 10, 40, 80) and intended use, ranging from very thin (e.g., 0.028 inches) to over 1 inch.
To clean a titanium pipe, use a solvent or contact cleaner such as WD-40 to remove dirt and residue. Wipe the surface with a soft, clean, dry cloth—preferably microfiber—to avoid scratches. For interior cleaning, a soft-bristled brush, like a slim wheel brush, can be used to remove carbon buildup without damaging the pipe’s surface.
